Try http://www.savagenews.com/drivers/drivers.html for drivers for the SiS 630/730.
The Asus V8420 is a high-performance version of the GeForce4 Ti4200.
(See http://www.hardocp.com/article.html?art=MzMx for a review)
It should work just fine with the "reference" drivers that Nvidia provides on their web site at
Although its performance as supplied is about the same as the other 4200s, the massive heatsink and higher performance memory means that it can be overclocked even more if you want.
I hope this helps a little.
Helden, thank you for your help.
I have unstalled the OpenGL 1.3, the Nvidia drivers from the site you gave me, and this is what says the Celestia help:
Vendor: NVIDIA Corporation
Renderer: GeForce4 Ti 4600/AGP/3DNOW!
Max simultaneous textures: 4
Max texture size: 4096
It seems that everything is working fien, but the planets rotation is flickering (I mean it seems to be no more than 5-8 images/second).
I have this results with the beta2 1.2.5 Celestia release, using only the default textures and bumps, nothing else.
What am I doing wrong?
Thank for the help.
Added later: I just thought I should add that I'm using one of the stardard 4200 boards without the Asus enhancements with only a 500MHz P3, and I don't think I see the flicker you mention. Motion is just a little jerky when I drag a planet around against a backdrop of *lots* of stars, but it's very smooth when I turn the stars off.
The only difference between what you report and what I see on my system is the "Renderer" line.
Mine says "GeForce4 Ti 4200/AGP/SSE"
"SSE" is the name of the graphics instruction set in the Pentium CPU.
"3DNOW!" is the name of the graphics instruction set in the AMD CPU.
They are very similar to one another, but not quite identical.
On the opening screen of v1.2.5b2, showing a full screen image of the Earth, when I turn on stars and galaxies with their brightness all the way up, my frame rate goes down to about 10-12 frames/second when I wigglie the mouse scroll wheel. With stars and galaxies off or dimmed all the way down, I get 50-60 frames/sec. Both rates are with antialiasing, pixel shading and vertex shading turned on. (Also, I'm using Pascal's new database of 780,000 stars from the Tycho catalog.)
The frame rate is shown in the lower left corner when you type the "back-apostrophe" (`). On U.S. keyboards, it usually is on the same key with the "tilde" (~).
Italian locale keyboards have a different layout than U.S. English locale. I don't know if Crhis' code makes allowances for this. (Of course, Windows should do the proper mapping, but maybe it is wrong.) You may need to use the key that's in the upper left corner of the keyboard. I think this is the "backslant" key (\) on Italian keyboards.
I hope this helps.
